4 / 16 page LMT87, LMT87-Q1 SNIS170A – MARCH 2013 – REVISED JUNE 2013 www.ti.com ACCURACY CHARACTERISTICS These limits do not include DC load regulation. These stated accuracy limits are with reference to the values in Table 1. PARAMETER CONDITIONS TYPICAL LIMITS (1) UNIT 70°C to 150°C; VDD = 3.0 V to 5.5 V 0.4 2.7 °C 20°C to 40°C; VDD = 2.7 V to 5.5 V 0.6 20°C to 40°C; VDD = 3.4 V to 5.5 V 0.3 Temperature Error (2) 0°C ; VDD = 3.0 V to 5.5 V 0.6 2.7 °C 0°C ; VDD = 3.6 V to 5.5 V 0.3 –50°C; VDD = 3.6 V to 5.5 V 0.6 2.7 °C –50°C; VDD = 4.2 V to 5.5 V 0.3 °C (1) Limits are specific to TI's AOQL (Average Outgoing Quality Level). (2) Accuracy is defined as the error between the measured and reference output voltages, tabulated in the Transfer Table at the specified conditions of supply gain setting, voltage, and temperature (expressed in °C). Accuracy limits include line regulation within the specified conditions. Accuracy limits do not include load regulation; they assume no DC load. ELECTRICAL CHARACTERISTICS Unless otherwise noted, these specifications apply for +VDD = 2.7 V to 5.5 V. Boldface limits apply for TA = TJ = TMIN to TMAX ; all other limits TA = TJ = 25°C. PARAMETER CONDITIONS TYP (1) MAX (2) UNITS Sensor Gain –13.6 mV/°C Source ≤ 50 μA, (VDD - VOUT) ≥ 200 mV –0.22 –1 mV Load Regulation (3) Sink ≤ 50 μA, VOUT ≥ 200 mV 0.26 1 mV Line Regulation (4) 200 μV/V IS TA = 30°C to 150°C, (VDD - VOUT) ≥ 100 mV 5.4 8.1 μA Supply Current(5) TA = -50°C to 150°C, (VDD - VOUT) ≥ 100 mV 5.4 9 μA CL Output Load Capacitance 1100 pF Power-on Time (6) CL= 0 pF to 1100 pF 0.7 1.9 ms Output Drive ±50 μA (1) Typicals are at TJ = TA = 25°C and represent most likely parametric norm. (2) Limits are specific to TI's AOQL (Average Outgoing Quality Level). (3) Source currents are flowing out of the LMT87/LMT87-Q1. Sink currents are flowing into the LMT87/LMT87-Q1. (4) Line regulation (DC) is calculated by subtracting the output voltage at the highest supply voltage from the output voltage at the lowest supply voltage. The typical DC line regulation specification does not include the output voltage shift discussed in OUTPUT VOLTAGE SHIFT. (5) The input current is leakage only and is highest at high temperature. It is typically only 0.001 µA. The 1µA limit is solely based on a testing limitation and does not reflect the actual performance of the part. (6) Specified by design and characterization. 4 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links: LMT87 LMT87-Q1 |
